====================
net/mlx5: Refactor esw QoS to support generalized operations

This patch series from the team to mlx5 core driver consists of one main
QoS part followed by small misc patches.

This main part (patches 1 to 11) by Carolina refactors the QoS handling
to generalize operations on scheduling groups and vports. These changes
are necessary to support new features that will extend group
functionality, introduce new group types, and support deeper
hierarchies.

Additionally, this refactor updates the terminology from "group" to
"node" to better reflect the hardware’s rate hierarchy and its use
of scheduling element nodes.

Simplify group scheduling element creation:
- net/mlx5: Refactor QoS group scheduling element creation

Refactor to support generalized operations for QoS:
- net/mlx5: Introduce node type to rate group structure
- net/mlx5: Add parent group support in rate group structure
- net/mlx5: Restrict domain list insertion to root TSAR ancestors
- net/mlx5: Rename vport QoS group reference to parent
- net/mlx5: Introduce node struct and rename group terminology to node
- net/mlx5: Refactor vport scheduling element creation function
- net/mlx5: Refactor vport QoS to use scheduling node structure
- net/mlx5: Remove vport QoS enabled flag

Support generalized operations for QoS elements:
- net/mlx5: Simplify QoS scheduling element configuration
- net/mlx5: Generalize QoS operations for nodes and vports

On top, patch 12 by Moshe handles FW request to move to drop mode.

In patch 13, Benjamin Poirier removes an empty eswitch flow table when
not used, which improves packet processing performance.

Patches 14 and 15 by Moshe are small field renamings as preparation for
future fields addition to these structures.
